The DAC9881EVM evaluation module (EVM) provides a powerful and affordable way to evaluate the features of the DAC9881 digital to analog converter (DAC). The device’s compact size and low-cost design make it ideal for use in low-power, high-frequency applications. The DAC9881 is capable of generating a wide range of signals, from a low 0.0V DC frequency to a maximum frequency of 78MHz. The DAC9881EVM integrates the DAC9881 into a single, low-cost board, while providing all the necessary components and features needed to quickly and accurately evaluate the device’s performance. With its wide frequency range and advanced signal processing capability, the DAC9881EVM is ideal for evaluation applications such as wireless communication systems, high-speed networking, audio and video processing, and audio/video production.

The DAC9881EVM utilizes a single-channel, low-power, high-frequency DAC core to generate analog signals over a wide frequency range. The DAC core includes a Decimation-Filter-Clock-Generation (DIFCG) module and a Sigma-Delta (SD) modulator, which are controlled by an on-board processor. The DIFCG module filters the incoming signal and converts it to lower-frequency samples. The SD modulator then processes the samples using pulse-code modulation to generate a low-frequency DC signal. This low-frequency signal is then converted by the DAC9881 into an analog output.

The DIFCG module can be used to control a variety of input signals. It supports a wide range of sample rates, providing for a variety of signal types and processes. The module also offers a variety of adjustments to control the bandwidth, time constants, and attenuation of the input signal. The DIFCG module is also capable of tracking multiple incoming signals.

The DAC9881EVM includes several additional components that are used to evaluate the performance of the device. The board includes a 12-bit Vga-to-dBm adapter and a function generator, which are used to accurately measure gains and adjust signal levels. The board also includes a signal generator and oscilloscope, which are used to generate and observe various waveforms and test signals. Additionally, the board features an Application Programming Interface (API) to facilitate the development of applications using the device.

The DAC9881EVM is a versatile and powerful solution for evaluating the features of the DAC9881 digital to analog converter. It provides an easy way to evaluate a wide range of signals and evaluate the performance of the device. The board features a range of evaluation components and an API, providing a platform for quickly and accurately evaluating the device’s performance. The DAC9881EVM is a great choice for applications requiring low-power, high-frequency signal conversion.
